Title: Improvements in or relating to apparatus for making electrical measurements upon coated conductors
Inventor: WALFORD HAROLD HUMPHREY THOMAS
IPC: G01R31/02
Filed: 1955-11-10
Abstract: 797,399. Electric tests. ADDISON ELECTRIC CO., Ltd. June 14, 1956 [Nov. 10, 1955], No. 32200/55. Class 37. The thickness and eccentricity of the coating on a conductor is measured by means of auxiliary electrodes which form condensers with the central conductor, the sum of their capacities indicating the thickness of the coating and their relative capacities the eccentricity. Fig. 3 shows a combined arrangement for indicating both thickness and eccentricity in which the electrodes 3 and 4 in spring-loaded contact with the insulating coating each form a condenser with the central conductor. These two condensers form a pair of adjacent arms of a bridge circuit of which the other two are formed by differential condenser 20. An alternating supply from oscillator 7 is applied across one diagonal of a bridge by a transformer 22 and the total current applied is a measure of the capacities of both condensers and therefore of the insulation thickness and is measured by a second transformer 9 having its primary also connected in the same diagonal and feeding a meter 26 through amplifier 24 and rectifier 25. The eccentricity is determined by sensing the unbalance in the bridge by means of transformer 16, the primary of which is connected across the other diagonal. This transformer feeds variable gain amplifier 27, phase-sensitive rectifier 28 and meter 30. In use, ganged switches are used to transpose electrodes 3, 4 and the terminals of meter 30 until the reading of this meter is the same in both positions. The gain of amplifier 27 is then adjusted in accordance with the reading of meter 26 when meter 30 indicates eccentricity directly. Switch 31 allows the D.C. output of rectifier 28 to control the gain of amplifier 27 directly if desired. A single amplifier phase-sensitive rectifier and meter may be used and may be switched to measure either thickness or eccentricity. A further arrangement may be used comprising a pair of electrodes at right angles to those shown. The output voltages from these arrangements may be used to operate alarm devices or to control an extrusion process.

Filed: 1926-12-23
Abstract: 287,631. British Thomson-Houston Co., Ltd., Young, A. P., and Hutt, J. Dec. 23, 1926. Loud-speakers; diaphragms ; magnetic instruments.-A device for the interconversion of mechanical and electrical vibrations, more particularly a loud-speaker, is provided with means adapted to neutralize, exactly or nearly, the weight of the vibratory element, in the direction of vibration, by the application of a contrary magnetic force which remains substantially constant over the working range of movement of the vibratory element. Fig. 1 shows a construction of loud-speaker in which a frustum shaped diaphragm 10 is very flexibly supported at its base 11 and carries actuating means 12 at its smaller end located in a magnetic air-gap 13. The actuating means 12 may either comprise a coil, as shown, or an annular magnetic member adapted to be influenced by oscillating currents fed to a coil or coils fixed in the face of the airgap. The weight of the movable element is counterbalanced according to the invention by means of an auxiliary coil 16 fed with direct current and preferably having an adjustable resistance provided in series therewith or by means of a member of magnetic material carried by the movable element and extending into tha air gap. According to a modification a direct current may be impressed on the moving coil 12 itself, or on a portion thereof. The diaphragm may be slidingly guided, as described in Specification 297,894, by means of a pin 21 on the central magnet pole 22 co-operating with a hole in a disc 23 closing the smaller end of the diaphragm. Fig. 3 shows a modified construction in which a conical frustum or saucer-shaped diaphragm 24 carries an operating coil 25 or ring magnet located in an annular magnetic air-gap 26. The magnet structure comprises a central core 28 having one of its ends surrounded by an annular pole-piece 29 which is joined to a flange 30 at the other end of the central core by longitudinally arranged cores 31 Each of the cores may be a. permanent magnet or may be provided with an exciting winding 32, as shown. The diaphragm, which is slidingly guided by a pin 33, has its outer edge 34 located in a groove 36 in a baflle 35. The edge 34 may be very flexibly connected with the baffle in order to prevent direct passage of the sound waves from one side of the diaphragm to the other or the groove 36 may be titled with cotton wool 37, velvet or like material. The weight of the movable element is counterbalanced by energizing the coil 25 with direct current as described in connection with Fig. 1. Sound-guiding means 38 parallel to the baffle and diaphragm direct the sound radially. The coil 25 may be carried by fingers bent out from the diaphragm. Specifications 231,420, 231,421. 245,796 and 269,804 also are referred to.

Abstract: 1,184,949. Ether-diamines. GLANZSTOFF A.G. 17 July, 1967 [2 Aug., 1966], No. 32725/67. Heading C2C. [Also in Division C3] Ether-diamines of formula where R is -O- or O(CH 2 ) n -O- and n is 2 to 4 are prepared and/or purified so that the content of impurities with an OH end group is reduced to less than 1 mole per cent prior to use in the preparation of polyamides (see Division C3). They may be prepared by the conventional process of adding the appropriate glycol to acrylonitrile at 25 to 40 C. in the presence of aqueous alkali to form the dinitrile, which is then hydrogenated in the presence of Raney cobalt to form the diamine. The desired purity is achieved by (a) extracting the dinitrile intermediate with chlorinated hydrocarbons especially chloroform, and rapidly distilling the extract discarding the first turnings; and (b) effecting the hydrogenation in the presence of solvents or diluents which are completely free from water or alcohol, e.g. benzene, toluene, cyclohexane or tetrahydrofuran. Pyrogallol may also be added to suppress decomposition during the preparation of the dinitrile. Example 1 describes the preparation and purification of ethylene-bis-(3-aminopropyl) ether via ethylene - bis - (2 - cyanoethyl) ether, itself prepared from acrylonitrile and ethylene glycol. The adipic acid salts of ethylene-bis-(3-aminopropyl) ether, the corresponding propylene- and butylene-analogues, and of bis-(3-aminopropyl) ether are also described.
